Problems solved by technology
The invention discloses a titanium dioxide precoated dynamic membrane photocatalytic water treatment device which mainly comprises a precoated dynamic membrane photocatalytic reactor 13 and a prereactor 16. The precoated dynamic membrane photocatalytic reactor 13 is internally provided with an ultraviolet lamp 9-1, a ceramic membrane tube 8 and a gas-distributing plate 7-1 and connected with a suction pump 1 and an air compressor 5 at the bottom, the prereactor 16 is internally provided with an ultraviolet lamp 9-2 and a gas-liquid distributing plate 7-2, and the precoated dynamic membrane photocatalytic reactor 13 and the prereactor 16 are connected by a water inlet pipe 14 and a water outlet pipe 12 to form a loop. By adding titanium dioxide precoated dynamic membrane to a floating photocatalytic reactor for integration, the invention not only has the advantages of great solid-liquid contact area, high reaction efficiency, simple precoated dynamic membrane preparation, full catalyst recycle, and the like, but also can effectively lessen the pollution of the ceramic membrane tube 8, prolong the operation period of the device, simplify the cleaning regeneration process of the ceramic membrane tube 8 and decrease the operation cost.
